New Physics of the $30^{\circ }$ Partial Dislocation in Silicon Revealed through {\em Ab Initio} Calculation

Gabor Csanyi, Torkel D. Engeness, Sohrab Ismail-Beigi +1

Based on {\em ab initio} calculation, we propose a new structure for the fundamental excitation of the reconstructed 30${}^{\circ }$ partial dislocation in silicon. This soliton has a r…
